T0 aZZ whom itm'og 015mm I Be it known that I, SIMON SNYDER; a citizen of'tlie United States; residing at Muncy, in the county of Lycomingandstate of Pennsylvania, have im 'ented certain new and useful Improvements in Feeding De vie-es; and I do hereby declare the follow ing, to be a full; clear, and eX'acIt"description of the 'invention, such as will enable others, skilled in the art to'wliicli it appertains to make and use the same.

This invention relatesto devices for use in feedinggranular materials such as flour, ground grain, and various feed materials or stock feed of various kinds in-measured or predetermined 'quantities; 'tlie device being especially desigi'ied andada'pte'd for" use in feeding andmixing different kinds of grain or other materials byineans'of a groupof adapted to hold a given amount or pred'e ternnned'quantity of lllfttel'lfll to be dis-- charged therefrom for admixture withfother materialcoming from another or other similar feeding devices, the pockets being so constructed that the filling or loading and discharging or unloading" the same in succession is accomplished more effectually and expeditiously than is possible with feeding devices of a somewhat similar character heretofore used for this purpose.

more particularly described, with reference to the accompanying drawings;which are to be taken as apart of this specification, and

then pointed out in the claims at the end of" the description. 7 In said drawings, Fig. 1 is a vertical sectional elevation of a feeding device embody ine' my invention; I

Fig. 2 is 'a perspective view of the feed drum detached;

such feeding devices "connected in 'gangaf.

The invention will first be hereinafter Fig; 3 is a vertical sectional elevation of a modified form of the device; i

I Fig; 4; is a perspective view of the modified form offeed drum shown in Fig. 3 and Fig. 5 is a diagrammatic view of'anot-her modification. j

Referring to said drawings, in' whichthe same reference characters areused to denote corresponding parts inv different views, {the letter A may denote a casingconstructed of wood or metal preferably metal, having side or end plates at in which suitable bearings are provided for the shaft of a feed: drum B rotatably mounted in said The or end plates a are c onnectedby suitable tie bolts 0, and; between said plates is secured a; curved plate a which extends in a gradual curve fron'i thefront upper-end of the casing downwardly and thence upwardly to the tie bolt near the rearvall of the-- cas ing which forms a support for the rear end of said curved plate, which forms, the front wall and bottom of the casing terminating. at suilicient distance from the rear wall of the casing to provide a discharge passage between said tie bolt and rear wall an open space being provided at the rearof the feed:

wheel or drum, between its periphery and the rear wall the casing, extendingupwardly from StllClPflSSEtgQ to a point abovethat at which thcpo'ckets begin to discharge their contents, so that said wall may not ob.-

struct or hinder :the passage of material through said space. A forwardly and downwardly inclined casing member or plate a is also secured between: the side plateso so as toform therear wall of a hopper with an open bottom which .discharges into the pockets of the feed. drum; said plate a terminatinga sutiicient distance above the plate to provide any open space through which the ground or com.

minuted material is delivered to the pockets ofthe fced drum. The bearings of the drum shaft may be of any suitable construction; such asare ordinarily used in milling machines; and therefore need not be specifically described or shown. The feed drum B as shownin Figs. .1. and: 2, consists of a central tubular hubslike member 6 having rigidly secured thereto or formed integrally thercwith between head platesi ,.a series of. curved radially extending pocket-forining vanes or'flanges b which. are curved in the direction of rotation on the arc of a circle we I that intersects the axis of the drum, so that the concave extremities or outer edges of two oppositely disposed vanes lie in substantially the same vertical or horizontal plane as indicated by the vertical line in Fig. 1 of the drawings, while the base of one of said vanes is arranged at one side of said axis and the base of the other vane on the other side of said axis, with the concave surfaces of the two vanes facing in opposite directions, thus adapting the vanes to scoop up the material as they move toward the hopper and moreefi ectually fill the pockets as the drum rotates than is possible in using feed drums as heretofore ordinarily constructed, or those having straight radial vanes, and as the drum continues to revolve, when the dis charge passage of the casing is reached; the convex surface of the next preceding vane in the series forms the bottom of the pocket for the time being and as it is curved downwardly it will begin to discharge the ground or comminuted material before the vane reaches a horizontal plane intersecting the axis of the drum, as indicated by the hori zontal line in Fig. 1, and the pocket will be emptied before the outer edge of the vane forming the bottom of the pocket for the time being has reached the rear end of the lower wall or bottom of the casing. it will be observed that the unloading operation is gradual and continuous, commencing at a point above the axis of the drum and continuing until the outer edge of the blade or vane forming for the time being the bottom ofthe pocket that is being unloaded has passed considerably below the plane of 7 said axis, thereby eii'ecting'a more perfect and uniform admixture of the material de livered by one machine with materials delivered by other machines in the group, each adapted to deliver a given quantity of material in a given period of time, than is possible in using machines of the same type as heretofore constructed and with greater accuracy in regulating the quantity of grain or other material to be measured and dc the vanes is spread over a larger surface than with vanes which. extend parallel with the shaft, and the stock is left in better condition for commingling with other grain or material discharged from other machines in the group. 7

But

In the modification shown in Figs. 3 and 4 the feed drum is formed with concentric tubular members 6 and b the inner one of which receives the drum shaft while the outer one has formed integrally therewith a series of pocket-forming vanes or'fianges b which are curved upon the arc of a circle as in the construction before described, so that a'line indicating a continuation of the curve will intersect the axis of the drum, as indicated in Fig. 3 of the drawings.

When used in a group, each machine may be provided with a spout emptying into the casing mouth or hopper, and with a discharge spout leading to a common outlet, for commingling or mixing the stock as it is discharged from the group of machines, or each machine may be provided with a separate discharge spout for conducting thestock mto separate receptacles, as may be desired in practical use.

Fig. 5 is a diagrammatic illustration of a construction in which there are a multiplicity of pocket-forming vanes, each of which is formed upon the arc of a circle intersecting the axis of the drum, for feeding finely comminuted materials, the operation of loading and unloading or filling and discharging being substantially the .same as hereinbefore explained with reference-to the lesser number of pockets shown in Figs. 1 to 4 of-the drawings.

Having thus described my invention, what I claim as new and desire to secure bvLetters Patent of the United States is 1. In a machine of the character described, a feed drum rotatably mounted in a casing having a feed hopper arranged to deliver material to the drum in front thereof, the front wall of said hopper being extended in a gentle curve downwardly and rearwardly and thence upwardly to a point at the rear of the drum near the rear wall of the casing and curved to conform to the curvature of the peripheral portion of the drum; an open space being provided between the periphery of the drum and the rear wall of the casing extending from a point considerably above the axis of the drum to the lower end of the easing, said drum being constructed with av hub-like central portion having a series of uniformly spaced pocket-forming blades or vanes projecting from said central portion in curved lines each struck upon substantially the arc of a circle intersecting said central portion at a point diametrically opposite the point at which another vane is joined thereto and having its concave surface facing the convex surface of the next preceding vane in the series, in the direction of rotation of the drum, whereby the vanes are adapted to'operate with a scooplike action in filling the pockets and to effect a gradual discharge of the contents of lliil lit) the pockets commencing at a point above the horizontal axis of the drum and continuing until the outer edge of the blade or vane forming the bottom of the pocket that being emptied has passed considerably below said axis substantially as described. i

2. In a machine of the character de scribed, a feed drum rotatably mounted in a casing having a feed hopper arranged to deliver material to the drum in front thereof, the front wall of said hopper being extended in a gentle curve downwardly and rearwardly and thence upwardly to a point at the rear of the drum near the rear wall of the casing and curved to conform to the curvature of the peripheral portion of the drum; an open space being provided between the periphery of the drum and the rear wall of the casing extending from a point considerably above the axis of the drum to the lower end of the casing, said drunibeing constructed with a hub-like central portion having a series of uniformly spaced ]')ockct--forming blades or vanes projecting from said central portion in curved lines each struck upon substantially the arc of a circle intersecting said central portion at a point diametrically opposite the point at which another vane is joined thereto and having its concave surface facing the convex surface of the next preceding vane in the series, in the direction of rotation of the drum, whereby the vanes are adapted to operate with a scoop-like ac-- tion in lilling the pockets and to effect a gradual discharge of. the contents of the pockets commencing at a point above the horizontal axis of the drum and continuing until the outer edge of the blade or vane forming the bottom of the pocket that is being emptied has passed considerably below said axis, said vanes extending lengthwise of the drum at an angle to its axis so as to adapt them to come into action at one end and continue gradually across the length of the drum toward the other end thereof, so that the filling and discharging action of the vanes is extended over a larger surface than with vanes which extend parallel with the shaft, substantial- 1y as described.

A machine for feeding granular material in measured or predetermined quantities, comprising a casing having a feed hopper at the upper front end thereof and a discharge passage at its lower rear end, and a feed drum revolubly mounted in said casing having a series of uniformly spaced pocket-forming blades or vanes which project from the axis of the drum in curved lines each struck upon substantially the arc of a circle intersecting said axis at a point diametrically opposite the junction therewith of another vane and having its con cave surface facing the convex surface of the next preceding vane in the series, in the direction of rotation of the drum; the front wall of said hopper being extended in a gentle curve downwardly and rcarwardly and thence upwardly to a point in substantially the same vertical plane as the free edges of said vanes at the rear of the drum and forming a hopper bottom of substantially the same curvature as the peripheral portion of the drum; an open space being provided between the periphery of the drum and the rear wall of the casing extending from a point considerably above the axis of the drum to said discharge passage, the mouth of said hopper and said passage being located on opposite sides of the drum in a plane extending diagonally across said casing from the upper front end thereof to its lower rear end substantially midway of the drum; said vanes being adapted to scoop up the material at the delivery end of the hopper and to g adually discharge the same con'n'nencing at a point above the horizontal axis of the drum and continuing until the outer edge of the blade or vane forming the bottom of the pocket that is being emptied has passed considerably below said axis.

In testimony whereof I- my signature in the presence of two witnesses.
